WILLIAM H. HOOPER,'OF SWAMPSCOTT, MASSACHUSETTS, ASSIGNOR, BY MESNE ASSIGN MENTS, TO THOMAS G. PLANT, OF BOSTON, MASSACHUSETTS.

CHANNEL-MOISTENING DEVICE FOR SOLE SEWING OR FASTENING MACHINES.

To all whom it may concern.-

Be it known that I, WILLIAM H. HOOPER, a citizen of the United States, residing at Swampscott, in the county of Essex, State of Massachusetts, have invented an Improvement in Channel-Moistening Devices for Sole Sewing or Fastening Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to channel wetting or inoistening devices employed in connection with sole sewing or fastening machines in the manufacture of boots and shoes.

My invention is applicable to all types of sole stitching or fastening machines, it being equally immaterial whether said machines are of the McKay or horn type, or of that employed in welt sewing, fair stitching or for applying metallic fastenings.

In the types of machines to which refer: ence has been made, the fastenings employed are usually laid in a channel formed in the sole, and to cause the stock of which the sole is composed more readily to be penetrated by the fastenings or the fastening inserting devices, it should be suitably treated with a moistening liquid such, for example, as water.

As heretofore constructed some of the machines of the type referred to, are provided with automatic devices for supplying water to the sole channel during operation of the stitching mechanisms, the same acting either periodically or continuously. The periodic moistening devices are operated by being connected with a moving part of the machine and the continuous moistening devices supply water uninterruptedly during the operation of the machine by connection with the starting and stopping treadle, the movements of the latter opening and closing a controlling valve in the supply pipe of the moistener. The former type is objectionable owing to the constant wear of moving parts with consequent leakage and the latter type is objectionable owing to the fact that its operation is restricted solely to the times of starting and stopping the machine.

My invention aims to provide an efiicient Inoistening device that is not connected with the starting and stopping mechanism or the clutch treadle, but which may be operated upon starting the machine so as to insure Specification of Letters Patent.

Application filed June 5, 1906.

Patented June 2, 1908.

Serial No. 320,280.

supplying the tempering li uid to and in advance of the stitching or astening mechanism and permit it to remain continuously in operation until the release of the clutch or the actuation of the stopping mechanism when it may be cut out of operation either with or independently of the stopping of the machine.

The above, however, with other objects and features of my invention will be best understood and appreciated from the following description, when taken in connection with the accompanying rawings of a machine embodying one form of my invention and selected for purposes of illustration, its scope being particularly pointed out in the appended claims. I

In the drawings ;Figure 1, in front elevation, artially broken away, illustrates an embo iment of my invention, selected for urposes of illustration, inwhich the moistenmg device is used in connection with a waxed-thread chain stitch shoe sewing machine of the type used in the manufacture ofwelt and turned shoes; Fig. 2 is an enlar ed vertical section taken on the line 2-2, ig.

1, to show the mechanism for closing the valve of the moistening device and its cQnnections in normally closed or in inoperative position; Fig. 3, a similar view showing thevalve closing mechanism elevated in position to open said valve; Fig. 4, a detail on the line 4-4, Fig. 1, showingthe actuating lever for operating the valve mechanism; and Fig. 5, an enlar ed detail representing a bottom view of a channel guide constituting the nozzle of the moistening device.

In the particular embodiment of my inven tion selected for illustration herein and shown in the drawings, referring first to Fig. 1, the machine column A, its head B and the various workin arts supported thereon may be of any esired type of construction, as for example, a commom and well knownt pe of commercial machine of the waxedtliread chain stitch welt type employed upon welt and turned shoes.

The machine shown is o erated (see Fig. 1) from a friction driving disk, 1, fast on a power shaft, 2, which is suitably journaled in or at the base of the column, and is provided with a cooperating loosely mounted pulley, 3,'connected by a belt, 4, with an overhead pulley or drive wheel, 5, onthe main or operating shaft, 16, of the machine.

The disk, 1, and loose pulley constitute one form of a friction clutch the members of which, in accordance with the usual practice, are adapted to be moved into enga ement with or separated from one another by means of a suitable treadle, in the present instance, shown as a horizontal treadle, 6. This treadle is suitably mounted at the side of the machine upon a rock shaft, 7, and has an upright arm, 8, forked at its up er end to enga e the grooved periphery of t e hub of said oose pulley, 3, to cause the latter to be moved towardv and from the fixed disk, 1, at

will.

It will be unnecessary to give a detailed 'descri tion of the construction and o 'eration of the stitch forming mechanism of machine, as such is well known and understood. It will be sufficient here to refer to the usual channel guide 0, adapted to run in the channel of the sole and guide it into 0 erative position, the awl, 50, the needle irectly behind it (but not shown), the looper, 70, and a work sup ort, 18, all of which may be of usual and'we known construction and operation. While any suitable moistening liquid may be supplied, in the present instance, water is employed, the same being stored within a reservoir or tank, 9, suitabl mounted above and adjacent the stitc formin mechanism and having an outlet, 10 contro ed by a valve, 13, from which leads an outlet pipe, 11, communicating, in the present instance of my invention, w1th a longitudinal o ening or assage, 12, (see Fig. 5), in said'c annel gui e a. The outlet end of said passage is adjacent the lower end of said guide end, so that water flowing through said passage will be directed into the channel of the sole in advance of said awl and needle;

' By this construction the moistenin of the sole is restricted to the channel and t e subjacent parts of the sole, thereby preventing staining, spotting and buckling of the sole surface produced by the manual application of water, or where water is permitted to flow freely from a canbr funnel and supply pipe.

. My invention, however, is not limite to such construction and cgntemplates the employment of any suitable part ofthe machine as a nozzle to direct the moistening liquid to and upon the work.

. The amount or supply of water may-be regulated by the valve, 13 (Figs. 2 and 3), which is provided at the connection of the supply pipe, 11, with said tank, 9. This va ve is provided with a lever arm, 14, connected by a link or rod, 15, to a bell crank, 19, pivoted at 20 intermediate the ends of its long arm, to a bracket, 21, secured to .a fixed part of themachine, the vertical oscillatlons of this long arm, opening and closing said valve. For oscillating this bell crank, its short arm is rovi'ded with a slot, 22 to receive a slide b lock, 23, arranged to slide this instance shown but one, now to freely therein, (shown in dotted lines in Figs. 2 and 3). This block carries a roller, 24, loosely pivoted thereon by a stud bolt or pin, 25, which also forms the ivotal connection'for a rod or link, 26, WlllCll is operated by means of a suitable actuating lever, 27 (Fig. 4), here shown as a treadle lever. This lever is'not the starting and stopping lever of the machine but is pivoted as at 28 upon the foot of the column A having its outer or free end curved forwardly to a position, it may be, close beside the said starting and stopping treadle, 6 (Figs. 1 and 4), so that when desired-the two may be depressed or released simultaneously or either may be operated independently of the other.

By reference to Fgis. 2 and 3, it will be apparent that as the link or rod, 26, is elevated, the slide block, 23, will first rise to the top1 of said slot, 22, before movement of said be crank results, and that continued upward motion of said block will swing said bell crank to depress the link, 15, and said valve lever, 14,- to open said valve, 13, and permit water to flow to the channel guide. When however, the rod or link, 26, is permitted to drop the block, 23, will slide down the bell connections intermediate it and said valve, 1 3.

While my invention contemplates several methods or arrangements of suitable mech anism foro crating and controlling the movements of t 's rod, 26, I have, in the resilnt e escribed, though I wish it to be. understood that the invention is for any means for securing the results set forth and is not limited to the s ecific mechanism shown and described. The ower end of said rod, 26 (Fig. 4), has a roller-30, which rests upon an ed e cam, 31, pivotally mounted upon a bracket, 32, at the foot of the column, a guide, 33, being formed upon or connected with this bracket to direct the vertical movements of said rod, This cam has a portion of less diameter against which said roller, 30, normally rests and a highpart, 34, or portion of greater diameter, to which said roller is moved by the rotation of said cam, so that the rod, 26,

is elevated thereby. To rotate or oscillate this cam about its axis, it is provided with a pinion, 35,'which is in mesh with a vertical segmental gear or rack, 36, formed in a head, 37, at the inner end of said actuating treadle 2,7 and which is suitably slotted to receive said pinion, 3.5, the teeth of said rack, 36,

being formed at a side of said slot and causin rotation or oscillation of the pinion and sai cam upon elevation or depression of the tread end, 38, of said actuating treadle, The

outer arm of this treadle (see Figs. 1 and 4),

is curvedforwardly and its tread end, 38,

extends forwardly beside and slightly above 1 operative causing his foot to actuate both the tread end, 39, of the startingand stopging or clutch operating treadle, 6. Upon e ressing the former the pinion and cam -wil be rotated sufliciently to cause the rod said valve simultaneously or immediately preceding the starting of the machine by the treadles." In stopping the machine,. the treadend, 38, of the actuating lever, 27, must be elevated above the elevated or normal osition of the starting and stop ing I tread e (see Fig. 1) before the cam wil be turned suificiently topermit the roller to drop into the depressed or low part of, its cam, but which does not, however, move the bell crank to close the valve. By this arrangement such partial release of the friction clutch may be made as is desired to cause the stitching or fastening mechanism to o crate slowly upon diflicult portions of tl ie work or whenever desired, and such release may be made without permitting the tread end, 38', of the actuating lever to rise sufliciently to permit the drop of said roller, 30, and its rod, 26, to render effective the machine or power operated mechanism for clos ing the valve of the moistening device now to be described. Since the drop of the rod, 26, does not move the bell crank, 19, it is necessary to provide other means than said treadle, 27, and its connections to close the valve of the moistening device, and this means should not be a spring or its equivalent because of the unreliability of springs and the fact that they impose addltional labor in moving the parts against the operation of the spring. I have therefore provided the' main shaft with a cam, 29 (see Figs.- 2 and 3), the outer or active end of which normally clears said roller, 24, in either the high$t orlowest position of the latter, but as the slotted arm of the bell crank is elevated in opening the valve, 13, it is swung into such a position that the roller will move into the path of said cam, as its carryin block, 23, slides down in the bell crank s 0t, 22. During this movement the adjacent or active end of the rotating cam,

. 29, strikes said roller as the latter reaches the position indicated by dotted lines in Fig. 3 and knocks it down to the bottom of the bell crank slot, 22, simultaneously rocking or swinging the bell crank, 8, on its pivot positively or toward the right (Figs. 2 and 3),

causing theelevation'of the link, 15, and the valve lever, 14, thus shutting off the water.

both in construction and o eration of the starting and stopping tread e, thou h said means may be operated simultaneous y with the latter if desired or at any other; time.

My machine operates as follows :The starting treadle, 6, is depressed to cause the movable clutch member or said pulley, 3, to frictionally engage said rotating friction disk, 1, thereby rotating said pulley, 3, the drive wheel, 5, connected therewith, and operating the stitching mechanism in the usual manner. cause his foot to rest upon both treadles, so that the valve actuating treadle is operated simultaneously upon starting the machine toswing said bell crank to open the valve of the moistening device in the manner described. As long as both treadles are held depressed the stitching mechanism will continue to operate and the moistening device will supply water uninterruptedly in advance of said stitching mechanism to temper the stock operatedupon by the latter. If

desirable, however, the operative may, by

the depression of the actuating lever, 27, open the valve of the moistening device prior to or subsequently to the starting of the machine and he may cause it to be closed through the release of the actuating treadle,

27, either before or after the release of the starting and stopping treadle, 6. Thus the water may be caused 'to flow continuously, intermittently or it may be supplied eriodically during the operation of the mac he at such times as may be desired. The valve of the moistening device, however, can only be closed throu h the operation of the machine itself, the re ease of the actuating lever, 27, only permitting the roller carrying block to slide down the bell crank slot which by the position it assumes upon release-of said lever, causes the roller to move into the path of the rotating cam, 29, which by its rotation will strike said roller and close the valve of the The operative may if he so desire moistening device in the manner described.

while the machine .is in operation or the ve actuating mechanism being under the By using power va control of the operative.

operated means, such as the cam, toclose the valve or render the moistening device ineifectlve, the use of s rmgs for the same purpose is avoided t ereby producing a.

more reliable device and resulting in a saving of labor on the part of the operative as already pointed out. Furthermore, the

pply may be turned on or off at will, the 1 water tank or receptacle being mounted directly. over the stitching mechanism, a comparatively short length of p1pe is required to. connect it with the channel'g'uide or otherwork'support, avoiding the necessity for long sections of flexible pipe, which are carried in moistening device with any work guide or support which can be adapted for such use and the employment thereof in connection with any desired type ofleather working machine.

It will be obvious that my invention is not limited to the specific details or to the arrangement of parts herein shown for illus' trative purposes only, but that the same may be modified and varied within wide limits without'departing from the spirit thereof.
